'Improved Cleaning Devices for VVea-ther- Screens of Motor-Vehicles,&c., of which the following description, wherein reference is made tothe accompanying drawings, is a specification.

In connection with those motor cars and like road vehicles wherein aglass weather or wind screen is employed, through which the driver ofthe vehicle has to look in or der that he may guide such vehicle,considerable inconvenience is caused during heavy rain or stormy weatherwith sleet, snow and the like, by reason of the drivers view beinginterfered with on account of his inability to see through said screenand the matter accumulated thereon. To provide means whereby anyobstructing matter that falls upon said screen may .be readily andquickly removed therefrom by said driver or those in attendance is theobject of our present invention.

In order that our invention may be readily understood we have hereuntoappended sheets of drawings illustrative thereof, to which, by figuresand letters, reference is made in the following description.

Figure 1 is a front elevation of a weather screen for a motor car,having our improvements applied thereto. Fig. 2 is a sectional endelevation of parts shown by Fig. 1.

Similar letters and figures of reference indicate like parts in bothviews.

In the several drawings only the wind screen itself is illustrated, saidscreen being of one particular form, butit will be readily understoodtherefrom how our invention may be applied to other forms of windscreens and how modifications of our invention may be arranged withoutdeparting from the nature thereof.

manner of what is commonly known as a squeegee. This bar we arrange tobe traversed over the wind screenc preferably in a vertical direction.In'the arrangementillustrated by Figs. 1 and 2 the bar a is secured tolaterally extended flanges formed on slides or bearings d which engageflanged guiding parts e-lfixed upon the framework of the weather screen0. Connected to the slides d are chains 7 which pass over pulleys 9,these latter being fixed upon end portions of a shaft g (which may betubular) which also has fixed upon it another intermediate pulley ithaving flanges to guide the chain which takes over it. This chain hwhich takes over it has its inner end fixed thereto, while its other endextends over the guide pulley k for an appropriate distance to enable ahandle part b to be secured thereto, the cha n h being wound upon pulleyh in a directlon opposite to the winding of chains on pulleys g. This.handle part if is arranged to engage the spring clip k which will retainit when its chain is withdrawn from the pulley h as shown by Fig. 2, inwhich position it will have raised the squeegee a, b to its highestposition where it will support same until the attendant removes saidhandlejz to allow said scraper or squeegee to descend by gravity. Thisdescending of the squeegee has the effect of clearing the screen of allmatter accumulated thereon. The guide pulley k is made use of in orderthat when the chain It is moved during the operations of the squeegeeinto the position somewhat as shown in broken lines Fig.

, 2, the portion of chain 71. extending between the pulley k and k maybe kept from c'ontacting with the upper edge of the screen 0. The windscreen is shown as mounted in connection with a motor car having a coveror projecting part m upon which the bearings 2 for the several pulleysand spring 72. are fixed, but it will be seen that where a screen isemployed supported solely from beneath, pulley and chains may bearranged upon and along the upper part and edge of same so as to supportand allow the movements of the squeegee in the manner described. The.term chain is employed for the sake of brevity, and is intended toinclude any equivalent flexible connection.

Such being the nature and object of our means connected with theintermediate pulinvention, What We claim is ley for rotating the same.
